About Amerisleep

Amerisleep is one of the oldest mattress-in-a-box companies.

Founded in 2007, the company has set itself apart through high quality mattresses, innovative features and great customer service.

The company has been especially vocal about its efforts to be more environmentally friendly.

They have committed themselves to using eco-friendly materials and low impact manufacturing processes.

Headquartered in Scottsdale, Arizona, Amerisleep ships its mattresses to customers living in the United States and Canada.

Social Impact

Amerisleep is a step ahead of many other mattress companies when it comes to social responsibility, especially related to the environment.

Throughout its production chain, the company tries to stick to eco-friendly practices.

They go beyond standard requirements to create a product that is safe, high quality and good for the environment – and their customers.

Additionally, all of Amerisleep’s manufacturing is done in the United States, which provides opportunities to local workers. Keeping manufacturing in the US also goes a long way in ensuring that the highest manufacturing and environmental standards are maintained.

The company also works with local charities to provide beds to the less fortunate.

Purchase Process

To keep prices low, Amerisleep has adopted an online-only model.

They don’t have brick and mortar stores where you can go and test their mattresses, nor do they sell-through retail outlets.

There are two places online you can buy an Amerisleep mattress: on their official website Amerisleep.com and on Amazon.com.

The prices are usually the same on both sites. From time to time, though, you can find slightly-used mattresses on Amazon at a discount.

The most important step in the purchase process is to select your model, which determines the firmness level.

There are five mattresses to choose from: Liberty, Colonial, Independence, Americana and Revere.

They all feature similar foam technology and construction, but differ in terms of firmness and a few advanced features:

If you prefer a soft or medium soft mattress, then go with the Colonial or Independence.

For an firm or extra-firm firm mattress buy an Americana or a Revere.

If you are like 80% of sleepers today who prefer a medium-firm feel, then go with Amerisleep’s most popular mattress, the Liberty.

If you aren’t sure, then Amerisleep’s website will guide you to the best choice, based on your preferred sleeping position.

Once you make your model choice, you will be directed to the product page where you can learn more about the mattress, the trial period, read the warranty and choose your preferred size. Then, just place your order.

Advanced Memory Foam Technology

In an effort to offer a great sleeping experience, Amerisleep uses several advanced memory foam technologies to craft their mattresses.

The biggest challenge Amerisleep claims to have overcome is in turning memory foam – notorious for poor support and sleeping too hot – into a far more comfortable, bio-friendly material that fosters better sleep.

1. Variable Pressure Foaming

The memory foams used in Amerisleep mattresses are manufactured using a process called Variable Pressure Foaming or simply VPF.

VPF is a highly eco-friendly manufacturing process.

The mattresses are placed together in a specialized chamber, and any emissions are passed through carbon filters to remove pollutants before they are released.

Additionally, no harsh chemicals are used in the manufacturing process, and there are minimal volatile organic compounds (VOCs) in the foam.

All waste at the end of the process is recycled.

2. Bio-Pur memory foam

Ordinary memory foams, while plush and comfortable, tend to get too hot at night and may not offer the best support.

Amerisleep has formulated their memory foam to eliminate these downsides and to add a few more beneficial features.

The result is a slightly different type of foam called Bio-Pur.

Amerisleep calls their foam, ‘Bio’, because some of the petroleum components of standard memory foam have been replaced with plant-based materials. This makes for a better, more comfortable and far more eco-friendly mattress.

Bio-Pur foam is also a bit firmer and more resilient than first-generation memory foam, which provides better support.

Finally, Bio-Pur foam is more breathable than ordinary memory foam. It features an open cell structure that allows air to move freely within. This keeps the mattress cool, dry and smelling fresh.

Amerisleep’s American, Liberty and Revere mattresses are made with the original Bio-Pur foam, while Colonial and Independence utilize an updated variant called Bio-Pur+.

Bio-Pur+ provides better air circulation and cooling ability. According to the company, it has 70% more breathability than the standard Bio-Pur memory foam.

In addition to its open cell structure, Bio-Pur+ foam undergoes an extra process called reticulation. This removes remaining air-blocking membranes from the foam, which boosts airflow within the mattress.

3. Active Flex foam

This is another special foam formulation created to provide better responsiveness and support to the body.

It is used in the Independence mattress only.

4. Surface Modification Technology (SMT)

Used in Colonial and Independence, SMT is a technology designed to boost mattress support and comfort.

Textured channels are added to the bottom of the foam. One obvious result of this modification is better airflow, which helps wick moisture and heat away from the mattress.

Construction

Americana

This is the firmest of the Amerisleep mattresses. This 10-inch foam mattress is ideal for back and stomach sleepers and consists of two main layers designed to achieve a firmer than usual feel.

Bio-Pur foam (3″ comfort layer)

The open cell structure of Bio-Pur makes it several times more breathable than standard memory foam and better at adapting to the body for increased support.

Bio-Core foam (7″ support layer)

The high-density Bio-Core foam provides support to the sleeper as well as the mattress. It also plays a crucial role in preventing uncomfortable (and unsightly) sags and ensuring that the mattress lasts a long time.

Revere

The Revere is also on the firmer side of the scale, but has a medium-firm feel.

It is a good choicefor back and stomach sleepers who love a firm surface but with a bit of ‘hug’ to keep them in position.

To create the medium-firm feel, the engineers made Revere slightly thicker than Americana.

Bio-Core foam (9″ support layer)
The sturdy, dense foam foundation resists sagging through the years.

Liberty

The Liberty is their most popular model and the one we tested at home.

It measures 12 inches in thickness and contains one more layer than the Revere and Americana.

Bio-Pur foam (3″ comfort layer)
This layer forms the first line of comfort for the sleeper. It provides pressure relief as the plant-based foam adapts to your body contours and weight. Any heat and sweat generated by your body is quickly whisked away thanks to superior airflow.

Active Flex foam improves on the ability of the mattress to adapt and respond to your body. It provides both support and comfort while also ensuring enhanced air flow thanks to air channels at the bottom of the layer.

Bio-Core foam (9″ support layer)

This thick, dense foam layer provides support for the sleeper and helps the mattress last years.

Cover

Amerisleep uses a special type of fabric, Celliant, to craft all of their mattress covers.

Celliant is a special yarn containing 13 thermoreactive minerals that react to heat in a very unique way.

When you sleep on a mattress, your body generates heat. A good mattress cover will absorb this heat (if they have poor airflow) and/or release it (if they have good airflow).

But Celliant does something radically different: it transforms your body heat into infrared radiation, which escapes quietly from your bed.

In addition to dissipating heat, infrared light has been found to have several health benefits. It boosts blood circulation, improves rest, increases energy levels and helps to regulate body temperature.

With a Celliant cover on top, Amerisleep says you’ll enjoy a deeper and better sleep and wake up feeling healthier, happier and more energized.

The other online mattress I know of that uses Celliant technology is the Bear mattress, which was designed specifically for athletes.

Smell/Off Gassing

There is one problem that most foam mattresses share: They usually emit a slightly unpleasant smell when they are fresh off the factory line.

Unlike years ago, however, when store-bought mattresses emitted harmful VOCs (volatile organic compounds), the smell you may experience when you first open your Amerisleep mattress is not harmful at all.

Remember that Amerisleep mattresses are Certi-PUR certified, which means they are made without harmful components like ozone depleters and heavy metals.

The company also uses plant-based materials to replace some of its petroleum-based components in the mattress, which reduces off-gassing.

Additionally, they use a special GREENGUARD certified fire sock for fire protection all around the mattress.

These technologies do not completely eliminate off-gassing, however.

Some Amerisleep customers have complained of an unpleasant odor from their new mattress. Others say they smell nothing but a ‘new car’ smell. To each his own, I guess…

I noticed a slight ‘plastic-in-my-car’ smell, too.

If you feel the smell is particularly strong, the company advices that you air-out the mattress for a few days. This means leaving it uncovered in a well ventilated room such as the garage.

Don’t make this your only deciding factor, however: it was barely noticeably after a day, and, the smell dissipates completely within a week or so.

Americana

With the Americana mattress – the firmest of the bunch – there are two kinds of sleeping experiences buyers are reporting.

For people looking for just a firm mattress, the Americana was often too firm for their liking.

But for those with back problems, Americana seems to be a great choice.

Even if you are just looking for a firmer mattress, this one could prove firmer than you want.

Revere

This is the most popular firm Amerisleep mattress. It is on the firmer end of the scale, but not as extreme as Americana.

The Revere sleeping experience seems to be great for back and stomach sleepers, according to other reviewers.

As you would expect, reported sinkage is minimal.

The soft cover and the top Bio-Pur foam layer help create a soft cushion to balance out the extra firmness of the mattress.

Liberty

This is the most popular Amerisleep mattress sold today.

The Liberty falls right in the sweet spot of firmness: not too hard, and not too soft.

This makes it ideal for a wide variety of sleepers and is especially great for those who cannot sleep in a single position.

The sinkage is minimal: it’s deep enough to create a slight cozy ‘hug’ around my body contours but not so much that I can’t move around at will (which I do a lot of).

The main complaint that I and other reviewers have about the Liberty is its relatively poor edge support. The Liberty does not hold up that well when you sleep or sit near the edge.

This is the same problem the Purple Mattress suffers from, if you’re comparing the two. The Liberty isn’t as bad as Purple, but poor edge support can be a problem for couples and people who roll onto the edges of their bed at night (really active sleepers).

Colonial

With the Colonial, we start moving into the soft extreme of the firmness scale.

The Colonial mattress falls somewhere just behind Liberty on an increasing scale of firmness.

The combination of Bio-Pur+ memory foam and an Affinity Transition layer definitely gives this mattress more sinkage than usual.

This mattress is perfect for slim sleepers with sharp body contours and side sleepers who need more cushioning for their shoulders and hips.

You might think this mattress is too soft for most people, but honestly most people who’ve reviewed this mattress are pleasantly surprised by the firm support, despite the greater sinkage.

My only concern is whether this mattress is durable enough to last years without any damage. Soft foam mattresses are notorious for short lives.

To be fair, this is a concern with all new online mattress brands. Because they have been around for just a short amount of time, we have no option but to wait and see whether their decades-long durability promises hold up.

Independence

The Independence is the softest mattress Amerisleep has to offer.

Despite what you may think, the Independence does not feel like you’re stuck in mud at night. According to most reviewers, it still has a nice bounce to it. However, the sinkage on this mattress is more pronounced than the others.

The Independence is ideal for side sleepers and those who love a plush sleeping experience. Some say it is similar to those luxurious hotel mattresses that you sink into after a long trip.

Surprisingly, many reviewers claim the Independence has better edge support than the slightly firmer Colonial mattress, although not as good as most innerspring & latex mattresses.

Given its level of softness, not many people buy it.

Like the Colonial, the Independence is also a new product, which always raises the question of durability, especially for a very soft mattress. Will it sag too quickly? Will support deteriorate?

At this point, you’ll just have to trust their warranty (which, at 20 years, is outstanding).

Independence

20-Year Warranty

Amerisleep provides an exceptionally generous 20-year warranty on all of their mattresses.

During the first 10 years, the company promises to replace or repair the mattress at no cost to you. this is non-transferrable and the mattress has to be properly supported and used. Material and workmanship defects are covered.

During the final 10 years of the warranty period, the mattress is covered based on a pro-rated schedule. If the mattress needs to be replaced or repaired, you will be assessed a charge against your refund with the amount depending on the number of years you have owned the mattress and its original purchase price.
